Abstract: A user equipment (UE) may receive a downlink message from a non-terrestrial network (NTN) which may include one or more sets of terrestrial network (TN) cell reselection information. The one or more sets of TN cell reselection information may further include location information corresponding to one or more cells of the TN. The UE may determine its location and, in response to receiving the downlink message, compare its location to the location information corresponding to the one or more cells of the TN. The UE may then select, based on the comparison, a set of the one or more sets of TN cell reselection information and further perform a cell reselection procedure based on the selection.

Abstract: Embodiments of an integrated access and backhaul (IAB) donor, IAB node, and methods of communication are generally described herein. An IAB network may comprise a plurality of IAB nodes to operate as relays between the IAB donor and one or more User Equipment (UE). The IAB donor may, for each of the IAB nodes, allocate a plurality of subframes to the IAB node. Each allocated subframe may have a subframe type that is one of: a downlink subframe, an uplink subframe, a flexible subframe or a not available subframe. The IAB donor may transmit, from a central unit (CU) of the IAB donor to a distributed unit (DU) an IAB node over an F1 interface, a resource coordination request message that indicates the subframe types of the plurality of subframes.

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

Abstract: An apparatus of a next generation Node B (gNB) Distributed Unit (DU) comprises one or more baseband processors to transmit one or more retransmitted Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) received from a gNB Central Unit (CU) to a user equipment (UE), and to feed back not only a latest, in-sequence New Radio User-plane (NR-U) Sequence Number (SN) to the CU for Release 15, but also a highest, in-sequence successfully delivered/transmitted PDCP SN, optionally, with a NR-U SN up to which the reported PDCP SN should be applied, which can provide an exact range of successfully delivered/transmitted status for retransmitted packets even in case of DU's re-ordering based on PDCP SN before transmitting to the UE. The apparatus can include a memory to store the reported PDCP SN and NR-U SN.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.

Abstract: A centralized RAN architecture that includes lower layer transmission nodes (referred to as distributed units (DUs) herein) that connect to an upper layer RAN node (referred to as a centralized unit (CU) herein). A centralized RAN architecture may include a functional split, between the CU and DU, corresponding to the Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) layers. In one embodiment, a CU may store copies of downlink PDCP PDUs that are transmitted to a first DU. The CU may retransmit, to a second DU, those of the PDCP PDUs which were previously transmitted to the source DU but have not been acknowledged as successfully delivered by the source DU.

Abstract: Apparatuses, systems, methods, and computer-readable media associated with F1 interface arrangement configuration within a network that implements virtualized NodeBs are disclosed herein. In embodiments, one or more non-transitory computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by one or more processors, cause a centralized unit (CU) of an access node to generate a CU configuration update message, the CU configuration update message to include an indication of a transport network layer (TNL) address of the CU for which a TNL association between the CU and a distributed unit (DU) of the access node is to be added or removed, and cause the CU configuration update message to be transmitted to the DU. Other embodiments may be described and/or claimed.
